4.6 billion years ago

The study pushes back the clock on the origin of Earth's water by hundreds of millions of years, to around 4.6 billion years ago, when all the worlds of the inner solar system were still forming. Scientists had suspected that our planet formed dry, with high-energy impacts creating a molten surface on the infant Earth.

During aerobic respiration, electrons travel downhill in which sequence?
iris [78.8K]

Answer:

The correct answer will be option-B.

Explanation:

Cellular respiration is a slow process which produces energy from the oxidation of food components which could be glucose, fatty acids and proteins.

The process proceeds in four steps: glycolysis, link reaction, Krebs cycle and electron transport chain.

The energy molecules are produced when a high energy electron gets reduced and the released energy is stored in the form of energy molecules which could be ATP or energy equivalents like NADH and FADH₂.

These reducing equivalents donate its electrons during electron transport chain where the electrons flow to the last electron acceptor called oxygen.

Thus, Option-B is the correct answer.

5.01 Why is the cell membrane essential for cell homeostasis?
hodyreva [135]

A cell membrane does not actually maintain homeostasis by itself. The term homeostasis refers to maintaining a relatively stable internal environment inside of a multi-cell organism. Since the internal environment is the interstitial fluid that is around each and every cell, then homeostasis has more to do with what is outside of a cell than what is inside of it. :)
